Officers' Quarters with Attached Basement Area Railings, St George's Barracks

The Officers' Quarters at St George's Barracks, built between 1856 and 1859, is a disused structure made of yellow stock brick with lateral stacks and a flat roof. It features a double-depth axial plan and consists of a single storey with a basement. The building has a symmetrical front with a ground-floor band, cornice, and parapet. The façade includes a 7:8:7-window range, with entrances at each end that divide the front into three sections. These entrances have stone surrounds, bracketed cornices, overlights, and half-glazed doors, with margin lights and stairs leading to the basement area. The windows are fitted with rubber brick heads and 6/6-pane sashes on both levels. A square water tower is located at the southwest corner, supported by round arches.

Inside, the building contains dogleg stairs from the entrances, a central passage connecting the rooms, and original joinery, including panelled doors and plasterwork. The property is also notable for its attached cast-iron railings, which feature panels with diagonal bars at the entrance stairs and around the round basement areas.

Historically, the quarters housed officers and servants, as well as a mess. The barracks served as a transit station for infantry after the Crimean War and were designed to be bomb-proof due to their location just inside the Gosport Lines. This site is the only example of this type of barracks in the country and forms a complete group with the Lines earthworks, highlighting Gosport's significance in the defense of the Portsmouth dockyard.
